Introducing Our Startup Series: Shares, SEIS & Smart Structuring

Introducing Our Startup Series: Shares, SEIS & Smart Structuring

As a founder, navigating the early stages of investment, share structuring, and tax planning can feel overwhelming especially when you're focused on building something that matters. That's why we're launching a new content series designed to give UK startups and scale-ups clear, practical guidance on one of the most misunderstood (and most important) parts of growing a business: your equity.
Whether you're issuing your first shares, applying for SEIS advance assurance, or trying to understand how a cap table affects your next funding round, this series is for you.


Why Now?

The way people search for answers is changing fast. With new AI powered search experience already influencing what gets seen (and what doesn’t), it’s more important than ever for founders to find content that’s straight to the point, easy to understand, and actually useful.
At OnTheGo Accountants, we work closely with startup founders, investors and growth-stage businesses every day advising on share schemes, valuations, R&D claims, and everything in between. This series is our way of making that expertise available to more people.


What We'll Cover

Over the next few weeks, we’ll be releasing a five-part series covering:

1. SEIS vs EIS: Key Differences for Founders and Investors

Understand the tax reliefs, timelines and eligibility criteria that matter when raising investment.

2. SEIS/EIS Advance Assurance: What It Is and How to Get It Right First Time

A step-by-step guide to getting HMRC's early thumbs-up and avoiding common delays.

3. Investor Decks, Cap Tables and Compliance: Accounting for Investment

How to prepare for investor scrutiny and keep your books clean from the start.

4. Common Pitfalls That Delay SEIS/EIS Approval (and How to Avoid Them)

Real-world mistakes we’ve seen, and how to fix or avoid them altogether.

5. Founder FAQs: When to Issue Shares, How to Value Them, and What HMRC Looks For

Answers to the questions founders ask us the most (plus a few they don’t, but should).

Who This Is For

If you're a founder:

• Preparing to raise capital or issue shares
• Considering SEIS/EIS but unsure how to start
• Wanting to understand how share structuring impacts tax, compliance, and future funding this series is built for you.

It’s also a useful resource for accountants, advisors, and investors who want a clear reference point to share with clients or portfolio companies.
